I have been using Southwest Air Conditioning and Heating for about the last 14 years or so and they have always done a good job for me. Their employees show up on time and they are friendly, professional people. Most recently they came out to check the refrigerant level in the air conditioning system for me. I thought it might be low but it wasn't. I would definitely recommend Southwest Air Conditioning and Heating to everyone! They are a solid, reliable company!
